There are some techniques which are just physically, mechanically and practically impossible to apply on shorter/larger people. Trying to fit the technique to all shapes and sizes is a definite recipe for disaster. Just don't.

Good points, thanks. I haven't tried using it in randori yet, I just learned the technique the other night. I could only pull it off with 1 out of 3 ukes.

I like Tai-Otoshi too, but can't really do any of my throws against a resisting opponent too well yet. Sometimes I can get a pretty good Osoto-Gari, I think that comes from practicing a lot of rear kicks in karate. I am hoping to get a lot more practice in over the summer(only 1 night a week right now).
